Proposal #458 to recognise the priority of Forpus modestus over F sclateri passed today (12 Nov 2010).Proposal 458 - Forpus modestus has priority over Forpus sclateri
Proposal #461 passed 31 Mar 2011.Proposal 461:
Remove Busarellus from buteonine genera in linear sequence of Accipitridae and rearrange linear sequence on non-buteonine genera
Part a: Move Busarellus to follow Ictinia.
Part b: rearrange sequence of genera to follow Griffiths et al. (2007)
I was wondering what Van Remsen would do with the Leucopternis spp within the scope of failed proposal 459."...This leaves the unfortunate but temporary situation of having 3 Leucopternis with the genus place in parentheses currently residing next to their relatives in Buteogallus. The proposal to fix that problem (459) was defeated, so I will try to revive a version of that proposal as soon as possible."
Proposal #492 [revised] passed 25 Jan 2012: RECENT CHANGES.http://www.museum.lsu.edu/~Remsen/SACCprop492.html
The proposal is now to recognise Buteogallus for most of the group and Cryptoleucopteryx for a monotypic Plumbeous Hawk. Looks like a very sensible middle ground between lumping everything into Buteogallus vs. recognising a bunch of monotypic genera.
